SHOE nnnssrne MACHINE Application filed October 31', 1932. Serial no. 640,398.

. described in my Patent No. 1,881,036.

Another object of my invention is to provide amachine forvspraying shoe polishing composition on shoes when the latter are on the wearers feet, protectingat the same time the ankles above the shoe tons from the sprayed composition.

Still another ob]ect is to provide an auto matic control-of the spraying operation so that the latter cannot begin until theshoe is placed in the proper operating" position andthe ankles above the shoe tops are covered with a. protective shield. f a

My invention is morefully described in the accompanying; specification and drawing inwhich- Fig. 1 is a sectional elevation of my machine in itsinoperative positiomliig. 2 is asectional end view of the same 3 is a sectionalelevation of my machine in its operating position, Fig. 4 is a sectional end view of the same, Fig. 5 is a top view of the same Fig. 6 is a detail view of the liquid spraying nozzle, and Fi 7 is a similar view of the powder spraying; nozzle. I

' My machine consists of a box or housing 1 with a platform 2 for a sho-e 3. .The pla form is supported onacollapsible ortelescopic standard consisting of'ai plunger l slieably fitted in a tube 5. A spring 6 tends to keep the platform in a raised position resting against a horizontal rod 7 the ends of which are fastened in the sides of the box 1.

The housinghas covers 8 w'th lugs 9 slidably fitted on transverse rodslO supported in the sides of the box. The covers have trimmed portions 11 adapted to fit over the users ankleabove the shoe tops. Thick strips of sponge'rubber 12 are attached to the inner edges of the covers at the recesses 11.

Thin rubber strips 13 are attached under neath to the edges of the covers so as to insure a tight joint when. the covers are moved against the ankle. Springs 14 tend to keep the covers open soas to permit the foot with the shoe3 to'be inserted between these covers 7 and tobe placed 011 theplatform 2. The outer edges of the covers have lugs 15 hingedly connected with the ends of levers 16. The latter are pivoted in bracketsl'? at the sides of the box 1 and have resilient inner or lower arms 18 with rollers 19on the ends bearing against the sidesof a tapered block 20 on the end of a rod 21 attached underneath to the platform 2. i

V A. rod 22 with afpiston23 is attached to platform 2 and is fitted in a cylinder 24 the bottom portion of which isconnected by a pipe 25 with a well 26 for a'liquid shoeispraying co1nposition27." A ball valve 28 is placed at the bottom of the cylinder 24. An exhaust p1pe29 extends from the lower end of the the cylinder 24 into an intermediatewell 30 with outlet pipes 31 and 32. The pipe .31 isconnecte'd with the upper portion of a spraying well 83, and the pipe 32 is connectedwith a pipe 34 extending to outer nozzles of spray-1' in-g guns 35. The bottomof the well 30 is connected by-a pipe 36 withinner nozzles of the guns 35. Thepipe 34'is also connected with one outlet of a-two-way valve 37, the other outlet of which is connected with a pipe 38 leading to afshoe polishing belt for dusting the same, of apolishing' machine (not shown).

Themiddle portion of the valve 87 is connected by a pipe 39 with a receiver 4O for the compressed air delivered a small compressor 41 operated by an electric motor 42. Instead of having a special motor for'the compressor, the latter can be also operatively connected with a motor operating a polishing belt of a polishing machine, such, for instance as is described in my Patent No. 1,881,036, whichmay be placed on a common bed plate with housing'l. The motor 42 is also belted or otherwise connected with a pulley 43 of a nix'er shaft 44 in the well26. The valve 37 has ahandle 45 pivotally connected with the end of a rod 4-6 attached to the platform 2.

An additional nozzle 50 is supported on the The operation of my machine is as follows. 7

The users foot with the shoe 3 is placed on the platform 2 which then depressed until the plunger strikes the bottom of the tube 5. The plunger 22 in'the cylinder 2% forces achzvge of the shoe shining liquid through the pipe 29 into the reservoir 30 through the valve 48, and into the well 33 through the pipe 31. The valve 28 remains closed by the pressure from the liquid.

The air Valve 37 remained disconnected from the pipe 3% until the foot began to move down, and the compressed air from the receiver 40 was liowingthrough the "pipe 38 into the shoe polishing machine (not shown) for cleaning the rotating brush. At the end of the travel of the platform? the valve 37 is finally turned into the position shown in Fig. 3 when the air is disconnected from the pipe 38 and is connected with the pipe 34.

V The air forces the liquid from the well into the pipe 36 and into the inner nozzles of the spraying guns 35, the valve l9 being opened by the air pressure.

The compressed air also flows from the pipe 34 into the outer nozzles of the guns 35 thereby spraying the polishing liquid on the shoe. At the same time" the air will spray 'a'polishing powder from the box 51 by the spraying nozzle 50. The bottom aperture in the box 51 is made very small so that the powder does not flow when there is no air blast'from the nozzle 50. The powder will be directed only on the toe portion of the shoe. After the well 33 has been emptied the air Wlll flow throughthe pipe 36 and through the inner nozzles'of the guns 35 thereby cleaning them from the remaining liquid. This arrangement permits the use of a predetermined portion of the polishing liquid for each shoe and eliminates waste of this liquid, preventing also the excessive spraying which may'spoil the shine. The air, coming from the nozzles at the end of the one 'ation, tends to dry the polish on the shoe and to prepare same for the-next or polishing operation, to

be performed on a separate machine.

i The ankle above'the shoe tops is protected from the spray by the covers 8 which are moved together against the foot by the arms 16, when the tapered block 20 forces the rollers 19 on the ends of the 18 apart.

The sponge rubber strips 12 press tightly against the foot, and the thin rubber flaps 13, being pressed against the foot, afford additional protection, closing also a gap between i the edges of the boards 8. The motor-42 operates continuouslyand pumps the air by the compressor 41 into the receiver 10 through the pipe 47. It also turns the mixer shaft 43 in the well27 thereby stirring the polishing liquid and preventing its sedimentation.

When the shoe is withdrawn, the springs 14 move the covers 8 apart, the block 20 being rapid movement of the platform 2 thereby permitting a normal operation of the pump 23 and of the other'moving parts of the machine.

Important advantages of my machine are that it is automatic in its operation, a pre determined amount of the shoe shining liquid being used for each shoe thereby insuring an even and uniform application, the shoe being sprayed from all sides; also that the operating nozzles cannot become clogged by the drying liquid as the latter is cleanly'blown out at the end of each operation. The stockings are protected from the spray by covers, tightly fitting over the ankle-above the shoe top, the covers being self adjusting for difierent thicknesses ofthe foot.

A throttling valve 53 may be provided in the pipe 32 in order to reduce the air passage through this pipe and to retard the flow of with adressing liquidwhen said shoe is in a lowered position, covers slidably supported on top of said housing, levers pivotally connected with said'covers and extending to the bottom of said housing, a block attached to said platform and adapted topress on the lower ends of said levers thereby closing said covers around said foot when said platform is lowered, and resilient strips on the edges of said covers adapted to fit tightly over said foot thereby protecting same above'said shoe from said liquid.

2. In a shoe dressing machine, the combination with a housing, of aplatform for a shoe in said housing, said platform being adapted to be lowered under the pressure from a foot with'a shoe, means to apply a dressing liquid to said shoe when said platform is in a lowered position, covers slidably supported on top of said housing and trimmed to fit the ankle above said shoe, elastic strips on the inner edges of said covers, a resilient means for closing said covers around said foot, said means being adapted to be operated by the ise downward movement of said platform, and means to open said covers when said platform is raised.
